very cool, cant wait too play this game.

This really stunned me. That's some lengthy co-op!

Reminds me of how impressive Resistance 2's co-op was.

Conviction might just do extremely well with critics.

Wow, thanks seece, i now give a damn about this game, if its offline!

They announced another set of game modes under the group of "Challenge modes".

Alongside its freshly unveiled six hour co-op campaign, Splinter Cell Conviction is also set to include a number of standalone challenge modes. These will currently being referred to as Third Echelon Missions, and will be spread across a variety of six maps. These are based upon four levels seen within the co-operative campaign, and two that will be exclusive to the mode.

At the time of writing, four modes have currently been confirmed;
Hunter – Clear the map of enemies,
Infiltration – Clear the map of enemies, without being detected,
Last Stand – Protect an EMP warhead from waves of enemies,
Face Off – Two players go head-to-head, includes a number of customisable AI enemies spread throughout the map.

Both these announced additions to the game will be entirely welcome amongst fans, and we’ll be looking forward to seeing them in action as the titles release draws closer. Splinter Cell Conviction will launch for Xbox 360 and PC, on 23rd February 2010.

Sounds absolutely amazing. I loved the Spy vs Merc gameplay in Pandora tomorrow and the coop from Chaos Theory was great as well. The levels were designed fairly well for coop play. This seems to be bringing the best of all of the Splinter Cell games into one amazing package.

^^Wow. So a seperate co-op campaing and a set of standalone challenges. That is a lot of game content.

I want this game :(

added to the games i love to play from Xbox 360:
Gears 1 and 2
dead or alive 4
splinter cell conviction
maybe alan wake

I'd like something more family friendly/less dark in their as well, but you're dead on.  One potentially amazing game a quarter fits my life/time nowadays.

Great, this will shape up to be best action game next year.
